5 Signs of a Dying Car Battery

If your car's battery is dying, it might be time to replace it. This is a process many drivers dread and rightfully so because replacing car batteries can be expensive and stressful. The good news is that there are some warning signs you can identify to prevent a battery replacement down the line when an issue arises:
Bad Alternator Output
The best way to check your car's electrical system is to check the voltage output from the alternator. The voltage should be relatively constant and nearly constant throughout the working range of the car's engine; if there is no consistent and constant voltage with the starter, it may be time for an alternator and/or battery replacement. The alternator is an important component in keeping your car running smoothly.
Battery Appears Bloated
If your battery case looks bloated, there's a chance that the positive and negative plates are breaking down and can no longer hold a charge. This may indicate that you have a bad battery and should have it checked out by your mechanic. Remember to always wear safety goggles when handling batteries of any kind to prevent injury from any acid spills.
Your Vehicle Seems Sluggish
If your car doesn't start as quickly as it used to, or starts with difficulty, this may be due to an aged battery. Also, if your car doesn't shift gears smoothly – especially when starting to drive after sitting for a while – this can be due to a dying battery as well. Always get your battery tested if you notice a problem like this with your vehicle.
There's a Sulfuric Odor From The Battery
This is a sign that the electrolyte solution or plates are breaking down and dying. Although not always the case, a sulfuric odor means you should have your battery tested because it might need to be replaced soon.
You notice corrosion on the terminals

If you notice corrosion on the terminals, this is an indication that there is a bad connection in your vehicle's electrical system, and should be checked out immediately by a professional. There might be problems with your alternator, starter, or voltage regulator if this is happening, and should be addressed as soon as possible.
